It's an R reg 2.2 dT estate
I can't find a door lock button on the drivers door, the only button (I can see) is a button by the handbrake that has a picture of 4 doors on it. There is currently a flashing red led. If you turn the ignition on the flashing red led goes out. If you hold the button down the led stops flashing and is just lit. This button appears to lock and unlock the doors but thats it.
It doesn't seem to matter which way i push the button, which appears to be on some sort of rocker switch, the rears doors won't open , even though you can here them unlock
The child lock idea seems right as it is both rear doors, although you can't open them from the outside either.
anyone got an owners manual they could lock in?
